The S-Works Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics and lightweight design offer a ride quality that seemed unattainable. After eight generations and over twenty years of development, it is not just the fastest Tarmac ever created, but the fastest road bike in the world. Are you ready? Aero-Avantgarde: Here, we focus on the surfaces that truly matter aerodynamically, not just those that look good. With this philosophy, we have developed our most aerodynamic road bike to date. Yes, it is more aerodynamic than the Venge. The redesigned head tube of the Tarmac SL8 maintains airflow more effectively, thanks to a sharper surface at the front. We call it the Speed Sniffer, and it allows the streamlined cross-section of the head tube to generate significantly less air resistance. Additionally, in accordance with new UCI regulations, we have created the narrowest and most aerodynamic Specialized seatpost ever for the Tarmac SL8. This design lets the fast-moving turbulent air flow more cleanly around the legs, making it a bike with a sense for victory. MINIMAL WEIGHT, MAXIMUM AERO: The Tarmac SL8 leverages insights from the development of the Aethos to easily meet the UCI weight limit, all while maintaining a complete aero setup. Our team has crafted an incredible frame weighing just 685 grams—15% lighter than the Tarmac SL7 and lighter than any other bike on the World Tour. Even though Kasper Asgreen rode our Aethos, which has a frame weight of only 585 grams, it doesn’t count as a comparison. The new technical capabilities allowed us to optimize the weight of the down tube, seat tube, and rear end in the Tarmac, as the new frame shape distributes weight so efficiently that additional carbon layers for added stiffness are no longer necessary. LIGHTNING-FAST ACCELERATION WITH MORE COMFORT: With a remarkable 33% improvement in the stiffness-to-weight ratio compared to the SL7, the Tarmac SL8 takes legendary handling, aggressive responsiveness, and World Tour-proven geometry to the next level. The bike is stiffer at the bottom bracket, more precise at the handlebars, and more compliant in the saddle, setting new standards for performance and comfort in racing bikes. Our Rider-First Engineering™ concept ensures that every rider, regardless of size, enjoys the same quality of ride and handling. At the saddle, the Tarmac SL8 offers 6% more compliance. It glides smoothly over rough roads—unique in the high-stakes world of road cycling. Moreover, the 32 mm tire clearance allows for the option to use tires with more volume when conditions require it.
